RECREATION GROUNDS
A mat should be kept just outside the court door.
Courts should not be kept shut up for long periods, but thoroughly
aired by opening doors and windows at least twice a week.
SIZES OF GROUNDS
The sizes of grounds, with plans of the field of play, will be found
in the relative games sections.
It should, however, be borne in mind that the maximum sizes are
given; where space is limited, grounds should be constructed to the
minimum size required for cup ties, tournaments, and leagues, and
even smaller when to be used for practice games only.
Consideration of this point is important, as it will sometimes mean
the provision of an extra ground or grounds.
ASSOCIATION FOOTBALL
Ground.—The
maximum laid down by the Rules of the Game is
130 yds. x 100 yds., and the minimum 100 yds. x 50 yds. Average
League dimensions, 110 yds. x 70 yds. Length must be greater than
breadth.
For the Army Challenge Cup the maximum is 120 yds. x 80 yds.,
the minimum 110 yds. x 70 yds.
It is suggested that a ground of 110 yds. x 75 yds. will meet all Cup
requirements, and for practice the size of the playing area could be
reduced.
ATHLETICS
Two parallel lines 80 yds. long and 265 ft.
4-21-
ins. apart, joined by
a semicircle with a radius of 132 ft.
81
ins., will produce a track of
four laps to the mile by measuring one foot outside these lines.

NOTE.—The laying out of tracks with curves of radii less than 90 feet
is not recommended.
